BODIOA Page 1of 4 Family: RHIZOPHORACEAE (angiosperm) Scientific name(s): Anopyxis klaineana Commercial restriction: no commercial restriction WOOD DESCRIPTION LOG DESCRIPTION Color: light brown Diameter: from60 to 100 cm Sapwood: not clearly demarcated Thickness of sapwood: Texture: medium Floats: no Grain: straight Log durability: low (must be treated) Interlocked grain: absent Note: Wood light brown with pink or ochre shades. Grain sometimes wavy. PHYSICAL PROPERTIES MECHANICAL AND ACOUSTIC PROPERTIES Physical and mechanical properties are based on mature heartwood specimens. These properties can vary greatly depending on origin and growth conditions. Mean Std dev. Mean Std dev.

Except for special comments on sapwood, natural durability is based on mature heartwood. Sapwood must always be considered as non-durable against wood degrading agents. E.N. = Euro Norm Funghi (according to E.N. standards): class 5 - not durable Dry wood borers: susceptible - sapwood not or slightly demarcated (risk in all the wood) Termites (according to E.N. standards): class D - durable Treatability (according to E.N. standards): class 1 - easily permeable Use class ensured by natural durability: class 1 - inside (no dampness) Species covering the use class 5: No Note: Prone to blue stain. REQUIREMENT OF A PRESERVATIVE TREATMENT Against dry wood borer attacks: requires appropriate preservative treatment In case of risk of temporary humidification: requires appropriate preservative treatment In case of risk of permanent humidification: use not recommended TROPIX 7 - © 1998-2011 CIRAD - Dissemination without express authorization is prohibited 26/03/2012 BODIOA Page 2/4 DRYING Drying rate: slow Possible drying schedule: 5 Risk of distortion: high risk Temperature (°C) Risk of casehardening: no M.C.

It must be used in compliance with the code of practice. For thickness from 38 to 75 mm, the air relative humidity should be increased by 5 % at each step. For thickness over 75 mm, a 10 % increase should be considered. SAWING AND MACHINING Blunting effect: normal Sawteeth recommended: stellite-tipped Cutting tools: tungsten carbide Peeling: not recommended or without interest Slicing: nood Note: Requires power. ASSEMBLING Nailing / screwing: good but pre-boring necessary Gluing: correct (for interior only) COMMERCIAL GRADING Appearance grading for sawn timbers: According to SATA grading rules (1996) For the "General Purpose Market": Possible grading for square edged timbers: choix I, choix II, choix III, choix IV Possible grading for short length lumbers: choix I, choix II Possible grading for short length rafters: choix I, choix II, choix III For the "Special Market": Possible grading for strips and small boards (ou battens): choix I, choix II, choix III Possible grading for rafters: choix I, choix II, choix III FIRE SAFETY Conventional French grading: Thickness > 14 mm : M.3 (moderately inflammable) Thickness < 14 mm : M.4 (easily inflammable) Euroclasses grading: D s2 d0 Default grading for solid wood, according to requirements of European standard EN 14081-1 annex C (April 2009). It concerns structural graded timber in vertical uses with mean density upper 0.35 and thickness upper 22 mm.
